Bob-
<<Google for APRS1.1 and you will go right to it.>>
Except, according to your own page, the APRS-WG still had not voted to accept
the spec. You open the page by saying it was accepted, but well down you say it
isn't 100% final yet.
Since their latest published standard
http://www.tapr.org/aprs_working_group.html is shown as v.1.0.1 and that's over
five years old....They've left you as a chorus of one. An unpublished,
unratified, standard proposal is not a standard.
"THE" standard, as officially accepted and announced byu APRS-WG, is still 1.0.1
and if that's incorrect, you folks really ought to figure out how to *publish*
standards.
